ROPE-CLAM P.

SPECIFICATION forming part of Letters Patent No. 405,686, dated June 18,1889.

Application filed May 14, 1888. Serial No. 273,834. (No model.)

To aZZ whom it may concern:

Be it known that I, ADAM VoLK, a citizen of the United States, residingat Lockport, in the county of Niagara and State of New York, haveinvented certain new and useful Improvements in Rope-Clamps; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

My invention relates to an improvement in rope-clamps designed for anenlarged variety of uses, and particularly adapted for use in connectionwith fire-escapes; and the object of the invention is to provide adevice of the character mentioned, whereby the rope may be quickly andeasily clamped and unclamped.

A further object of the invention is to provide a device of thischaracter which shall be simple in its construction, cheap tomanufacture, and strong and durable.

With the above objects in view the invention consists in thecombination, with a sectional head, of a handle or handles for operatingthe same to clamp a rope.

The invention still further consists in the features of construction andcombination of parts, as will be hereinafter more fully described, andpointed out in the claims.

In the drawings, Figure 1 is a perspective view of a rope-clampembodying my invention. Fig. 2 is a transverse vertical section of thesame, and Fig. 3 is a horizontal section on the line 00 w of Fig. 1.

Corresponding parts in the several figures are denoted by the sameletters of reference.

Referring to the drawings,A represents the clamp, which consists of ahead B and suitable handles C, for operating said head to clamp therope. The head B consists of two parts or sections a b of any desired orsuitable length. Each of the parts or sections a b is formed with agroove or depression c,ex-

tending its entire length, thereby forming a channel for the passage ofthe rope to be clamped. The said parts or sect-ions a b of the head arealso formed on their outer faces, near their upper and lower ends, withgrooves 0r depressions d, and fitting in said grooves or depressions arecollars e, which encircle the head. The said collars each have anextension on one side, and said extensions are received between thebifurcated ends f of ferrules g, fitted on the ends of handles 0.

The sections a b of the clamp may be formed with ears or lugs z, havingsuitable perforations for the attachment of any desired device thereto.

The collars e are formed eccentrically on their engaging faces, and thegrooves 11 are similarly formed, so that a slight turn of the handlesserves to bind the head on the rope at each end, while a slight turn inthe reverse direction serves to loosen the clamp and permit the rope toslide therethrough.

A clamp constructed as above described is simple, cheap, and durable,and its operation thoroughly positive and effective.

Having thus fully described my invention,- what I claim as new, anddesire to secure by Letters Patent, is-

1. A rope-clamp consisting of a sectional head having an eccentricgroove or grooves and a handle or handles having each a collar,substantially as set forth.

2. A rope-clamp consisting of a sectional head having eccentric grooves,handles having collars formed with eccentric openings, andattaching-lugs on the head,substantially as set forth.

In testimony whereof I have aifixed my signature in presence of twowitnesses.
